I HAVE A CDL SO I AM ABLE TO COMMENT WITHOUT BEING IGNORANT. A FEW WORDS ABOUT ROAD SAFETY FOR CARS, AS FOLLOWS; DO NOT HANG NEXT TO A BIG TRUCK WHILE YOU ARE PASSING. THERE IS A BLIND SPOT WHERE THE TRUCK DRIVER CAN NOT SEE YOU ,ALSO IF ONE OF THOSE REALLY BIG TIRES BLOWS WHILE YOU ARE RIGHT NEXT TO IT, THE IMPACT COULD CAUSE YOU TO RECK, THEREFORE MAKING YOU DEAD OR INJURED.
